Round nose bullets are often accurate because they engage the lands much sooner than more pointy bullets. They're a close range affair though.
I really like them in my Savage 1899s and other rifles.
I'm not sure what would be considered long range, in my neck of the woods 2-300yds is a long shot. The RN bullets i've used in 7mm, .308 and .277 can handle those ranges with ease, especially in the right cartridge.
